Abstract: A method for correcting service manual textual inconsistencies. Extracting textual procedures from service documents stored in a memory of a service document storage device. Each term of an extracted textual procedure terminology is compared to a correlating target name terminology for identifying any matching terms by a processor. An overlap similarity is computed as a function of the identified matching terms from the extracted textual procedure terminology and the correlating target name terminology. A determination is made whether the overlap similarity is greater than a predetermined similarity threshold. The service documents are modified to change the extracted textual procedure terminology to the correlating target name terminology in response to the overlap similarity being greater than the predetermined similarity threshold and the extracted textual procedure terminology not exactly matching the correlating target name terminology.

Abstract: A method of detecting a misfire condition in a spark ignited internal combustion engine where the idle speed of the engine is controlled by an idle speed control means which controls engine idle speed by varying the spark timing advance for the engine ignition system. With the engine running at idle speed, the instantaneous spark timing advance being developed is repeatedly sampled for a predetermined number of consecutively occurring data samples. The absolute difference in sampled spark timing advance values between each pair of data samples is calculated for all of the predetermined number of data samples. The absolute differences in spark timing values that occur between data samples are added together to provide a sum total. If the sum total exceeds a reference value, the engine is operating in a misfire condition.
